CLINICAL AND LABORATORY ASSESSMENT OF TREATING CARIES IN CHILDREN'S PERMANENT TEETH USING VARIOUS ADHESIVE SYSTEMS

Subject. Children's permanent teeth affected by caries at various stages of hard tissues mineralization. Objectives. To substsantiate the choice of various adhesive systems to treat dentine caries in permanent teeth with carious lesion of average intensity in incomplete and completed processes of hard dental tissues mineralization. Methodology. Clinical examination and treatment of 151 children (287 permanent teeth) for dentine caries (K02.1) aged 7 to 15 was carried out. Assessment of seals marginal integrity was carried out according to G. Ryge (1998) and using electrometric method. Results. In children's permanent teeth with incomplete processes of hard tissues mineralization, with total etching technology, unsatisfactory restorations frequency after 2 years was 21% and 57% with self-etching adhesive used. In group with total etching technology, electrical conductivity after 2 years was 42,8% lower than in that one with self- etching adhesive system. In children's permanent teeth with completed processes of hard tissues mineralization, unsatisfactory restorations frequency after 2 years was almost equal and amounted to 27% and 30%, respectively, in both groups with no significant differences in electrical conductivity rates. Conclusion. In children's permanent teeth with average carious process intensity and incomplete hard tissues mineralization processes there is a denser adhesive compound with total etching technology and in permanent children’s teeth with completed hard tissues mineralization processes there are no significant differences in marginal adhesion of fillings to dental tissues when self-etching adhesive technology of total etching is used.
